Abstract
The invention relates to an embedded plug-in connector, which is suitable for realizing a plug-in connection which can be locked mechanically and is matched with a cable plug-in connector matched with the embedded plug-in connector as a matched piece, wherein signal transmission is realized through a closed plug-in connection. According to a first aspect, the embedded plug connector is implemented with a first part and a second part, for example in at least two-part fashion, wherein the two parts are adapted to be directly fixed to the mounting plate. According to another aspect, the embedded plug connector has a top cap, alone or in combination with a two-part form, wherein the top cap cooperates with a flange adapted to be mounted to a mounting plate in a manner such that a labyrinth seal and a contact seal are formed in a closed state of the top cap. In this case, this labyrinth seal provides the first sealing stage with a throttling effect. A contact seal having an elastomeric seal assembly provides a second seal stage downstream of the first seal stage.
Description
Technical Field
The invention relates to an embedded plug-in connector for the exact-fit realization of a mechanically lockable plug-in connection with a cable plug-in connector which cooperates as a mating part with the embedded plug-in connector (such that the embedded plug-in connector and the cable plug-in connector each form a plug-in connection mating part with one another), wherein signal transmission is realized by means of a closed plug-in connection. The invention relates in particular to an embedded plug-in connector for a plug-in device which can be plugged under load and stress.
Background
The embedded plug-in connector (also referred to as a chassis receptacle) is adapted to be mounted in a housing, a switchboard, or similar device of an electrical apparatus to provide signal transmission or conductive connection between the apparatus or apparatus components. The signal transmission or conductive connection is produced by inserting a mating piece (complementary plug connector) complementary to the plug-in connector into the plug-in connector. Complementary plug connectors are for example designed as cable plug connectors for connecting cables to plug-in connections, wherein mechanical locking generally prevents an undesired loosening of the connected cables and thus an undesired removal of the electrical connection. The signal transmission may be realized, for example, electrically (e.g., via a copper cable connection) or optically (e.g., via a glass fiber connection).
Such embedded plug-in connectors are used, for example, for broadcasting and measuring technology, for example for audio and video measuring technology used, for example, in television stations or stage technology. Other fields of application relate to the fields of lighting, networking, PA, military, rail traffic, petrochemical, and the like.
The plug-in connection is suitable for the conditions of larger load or worse environment. These plug-in connections are specifically designed for this purpose, for example, in order to be resistant to environmental influences in the plugged and unplugged state. The phase, neutral and protective ground wires are typically protected from accidental contact and the plug is latched from accidental removal. Furthermore, it is often required that plug-in connections can be made under load and stress until a predetermined current-carrying capacity is reached.
There are two embodiments of the plug connector: in one aspect, in embodiments for signal input, for example, the grid voltage is input on the device; on the other hand, in embodiments for signal transmission, for example, the grid voltage is transmitted from one device to another. The term "embedded plug connector" is understood hereinafter to mean both an embedded plug connector for signal input and an embedded plug connector for signal transmission, unless otherwise indicated.
Prior art embedded connectors, such as the powerCON product family from Neutrik AG (Schaan Sha En, liechtens list) generally each include a housing having an insertion opening for a complementary plug connector, wherein a protruding connecting flange is provided on the insertion-side end of the housing, which has a recess for the passage of a securing member. A flange is also provided on the insertion side with an insertion opening for a complementary plug-in connector and a mounting hole for connection with a device wall, a switchboard or the like.
EP 3,514,892 B1 describes a typical plug-in connection between an embedded plug-in connector and a cable plug-in connector, wherein this plug-in connection is blocked against accidental release of the cable plug-in connector, the embedded plug-in connector and the cable plug-in connector having key element fittings or key elements which mate with each other such that the cable plug-in connector can only be plugged into the embedded plug-in connector in a specific rotational orientation.
During operation, the plug connection is often subjected to large mechanical loads, which may, for example, lead to increased play when connecting the complementary mating parts into the embedded plug connector or may also lead to breakage of the plug part.
The plug-in connectors generally have, for example, guide means which cooperate with key elements of the cable plug-in connector which cooperate with the guide means, so that the cable plug-in connector can be plugged into the plug-in connector only by means of a specific rotational orientation preset for the key cooperation. Due to the frequent undocking and reinsertion of plug-in connections, such as during stage construction of a tour, these guides wear out, so that the probability of incorrect combinations or poor contact of the embedded plug-in connector and the cable plug-in connector and the probability of non-sealing connections occurring due to environmental influences increases.
In addition, the high time pressures and desired flexibility of stage performance often lead to rough handling of equipment by artists and constructors. It is therefore common for construction personnel to climb up on or through the housings of inserted cable plug connectors in order to reach higher positioned equipment, such as higher positioned loudspeakers of a loudspeaker column.
Furthermore, the plug-in connection has to withstand dust, water and corrosion effects, and therefore the prior art plug-in connectors have different sealing concepts in order to protect the plug-in connector and the adjoining electronics from external influences in the plugged-in state as well as in the idle state. In this case, the complexity generally increases with the desired (higher) seal level, with increasingly higher demands on the manufacturing tolerances of the individual plugs and seal assemblies. In the event of an increased complexity of the sealing device, the frequent connection and disconnection of the embedded plug connector and the cable plug connector again causes wear and failure of the desired sealing effect.
The basic structure, in particular the external dimensions, of the embedded plug-in connector are the same worldwide, the embedded plug-in connector and the cable plug-in connector being standardized in a way that the economical pressure does not practically deviate from this structure in terms of compatibility between products of different manufacturers. Thus, any mating of the embedded plug connectors (as well as the cable plug connectors) is subject to stringent boundary conditions in terms of geometry and space requirements. Limitations associated with the drilling and installation dimensions of the embedded socket are in particular severely limited in order to ensure mechanical compatibility with equipment walls, switchboards etc. made according to known preset values. For example, if the flange is too large or has an abnormal shape, a certain number of the insert connectors cannot be placed side by side with each other on a preset space as in the prior art.
Disclosure of Invention
It is therefore an object of the present invention to provide an embedded plug-in connector which overcomes the drawbacks of the prior art, in particular in view of the strict specifications about the installation dimensions worldwide.
Another object is to provide an embedded plug-in connector which reduces the frequency of failures caused in particular by mechanical loads or by environmental influences.
Another object is to improve an embedded plug-in connector, which reduces the risk of incorrect connection of the embedded plug-in connector with the cable plug-in connector.
The solution to the above object of the invention is found in at least part of the characterizing features of the independent claims. Further improvements of the features of the invention in an alternative or advantageous manner can be seen from the independent claims and from some other features of the dependent patent claims.
The present invention relates to different aspects of an embedded plug connector adapted to achieve a mechanically lockable plug connection with a cable plug connector as a mating piece that mates with the embedded plug connector and that can be inserted into an opening of the embedded plug connector (such that the embedded plug connector and the cable plug connector are plug connection mating pieces with each other), wherein signal transmission is achieved by achieving a plug connection between the embedded plug connector and the cable plug connector. For example by implementing a plug-in connection to enable the conduction of signals for a power supply or the transmission of audio signals.
The basic structure of the embedded plug-in connector is adapted in such a way in all aspects that this embedded plug-in connector is adapted to be fixed to the mounting plate and to be fixedly carried by the mounting plate in the mounted state on the mounting plate. In this case, this mounting plate has a mounting plate recess for the embedded plug connector and/or the cable plug connector, and the embedded plug connector is adapted to be placed and supported on the region of the mounting plate surrounding the mounting plate recess. The mounting plate has a front face, which faces somewhere, from where the cable plug connector can be guided onto the embedded plug connector in a mounted state on the mounting plate, and the mounting plate has a rear face facing in the opposite direction.
According to a first aspect, in addition to this basic structure, the embedded plug connector has a signal transmission contact element which is adapted to effect signal transmission across the plug connection by effecting contact of the plug connection with a cable plug connector side signal transmission contact element mating piece. The plug-in connector further has a supporting enclosure for providing a supporting effect for the cable plug-in connector (in the plugged-in state) with respect to a load force acting on the cable plug-in connector perpendicular to the plug-in direction of the cable plug-in connector (such as a shearing and/or pushing load of the cable plug-in connector) in the state created by the plug-in connection.
The embedded plug-in connector is implemented in at least two parts with a first part and a second part, wherein the two parts are adapted to be directly fixed to a mounting plate. For direct attachment to the mounting plate, the first part has a first part flange for placement onto the back side of the mounting plate and the second part has a second part flange for placement onto the front side of the mounting plate. Furthermore, the first part has signal transmission contact elements. The second part has a support enclosure region, wherein the support force exerted by the support enclosure region, which counteracts the load force, is at least partially carried by the mounting plate in the mounted state of the second part by means of the direct fastening of the second part to the mounting plate in a predetermined manner.
By means of the two-part form and the arrangement of the signal transmission contact elements in the first part, the load forces acting on the embedded plug-in connector transversely to the direction of insertion of the cable plug-in connector can be decoupled at least in part by the assembly of the embedded plug-in connector which is suitable for electrical and mechanical connection with the cable plug-in connector, in particular in that the main load of these load forces can be carried by the second part arranged on the front side of the mounting plate. Thus, the forces acting on the electrical and mechanical connection components of the embedded plug connector are reduced, for example by lateral loads applied to the inserted cable plug connector. Furthermore, the mechanical strength of the second part with respect to the loading force and the mechanical strength of the entire embedded plug-in connector are further increased by the direct fastening of the second part to the mounting plate, since the loading force can be transmitted substantially directly to the mounting plate by the direct fastening.
Furthermore, by means of the two-part form and the arrangement of the signal transmission contact elements in the first part, the space required, which may be created by fixing the intended borehole and the mounting dimensions, can be better utilized.
In the prior art, the drill holes and the mounting dimensions of the embedded plug connectors for signal input are different from those of the embedded plug connector parts for signal transmission (signal output). The power supply plug-in connectors suitable for signal output have, for example, larger drill holes and installation dimensions than the power supply plug-in connectors suitable for signal input, wherein the latter drill holes and installation dimensions correspond to those of other widely used plug-in connector types, for example plug-in connectors for conducting audio signals. The difference between the current signal output plug and the current signal input plug (and other types of input and output plugs) is essentially undesirable, simply due to the lack of a more compact structural solution for the signal output plug-in connector. Therefore, based on strict specifications regarding the installation dimensions established worldwide, in the prior art it is advantageous to adapt the power output plug to the dimensions of other embedded plug-in connectors. The usual dimensions of the insert connectors are the so-called D-dimensions, which set a flange with a side length of 26mm (flange width) x 31mm (flange length) and a bore hole with a diameter between 23.6 and 24 mm.
By means of the two-part form and the arrangement of the signal transmission contact elements in the first part, for example, a supporting sheath connection between the plug-in connector assembly arranged on the front side of the mounting plate and the plug-in connector assembly arranged on the rear side of the mounting plate is not required. In order to achieve the decoupling of the transverse forces acting on the electrical and mechanical plug-in connector assembly (transversely to the direction of insertion of the cable), which is mentioned at the outset, it is particularly advantageous if the front and rear assemblies of the plug-in connector are not connected to one another in a supported manner, if the forces are absorbed by a second part arranged on the front side of the mounting plate, which part has a supporting enclosure region. This allows the entire width of the borehole to be used to pass through the cable plug connector. This enables the design of the embedded plug connector for drilling and installation dimensions for other widely used embedded plug connector types. For example, a power outlet plug may be provided for installation with the more usual drilling and installation dimensions of the power outlet plug and the audio plug, for example with a design according to the so-called D-dimensions (flange side 26mm x 31mm, drill diameter 23.6-24 mm).
Thus, for example, it is not necessary for a jacket element (an outermost delimiting element, such as an outermost side wall portion, facing the inner wall of the mounting plate recess) to protrude into or through the mounting plate recess in a state mounted on the mounting plate in such a way as to adjoin the inner wall of the mounting plate recess, in order in this case to separate the inner region (perpendicular to the insertion direction) of the plug from the inner wall of the mounting plate recess by the jacket element (facing the insertion axis). The cross section to be provided for the plug-in connection of the cable plug-in connector, i.e. the minimum mounting plate recess size, may be limited only by the cable plug-in connector.
In one embodiment, the first part has a mechanical holding element which is adapted to prevent an axial displacement of the cable-plug-connector-side holding-element fitting in the cable-plug-connector extraction direction within the frame of the first part of a locking mechanism which can be actuated by a rotation of the cable plug-connector in the screwing-in direction in the state in which the cable plug-connector is at least partially inserted into the plug-in connector. Furthermore, the second part has a mechanical closing element which is adapted to be in the frame of the second part of the locking mechanism, so that the latch of the cable-entry connector, which is connected to the latch slide, snaps into this closing element, which locking mechanism can be actuated by moving the cable-entry connector-side latch slide. This prevents the cable-inserted connector from rotating in a unscrewing direction opposite to the screwing direction.
This holding element is arranged and constructed, for example, in such a way that the holding element fitting snaps behind this holding element after actuation of the first part of the locking mechanism.
In another embodiment, the mechanical holding element is constructed as a groove means (e.g. a rail or notch means). The recess of this recess means extends first of all axially, thereby serving in particular as a key fitting for a key element of a cable plug connector. These grooves then extend perpendicularly to the axis or slightly obliquely perpendicularly to the axis and serve as retaining elements in this region, wherein the retaining element fitting is constructed as a flange arrangement which is inserted into the groove structure by means of the plug-in connection and which prevents axial extraction by means of the groove arrangement region extending perpendicularly to the axis or slightly obliquely perpendicularly to the axis.
Alternatively, the mechanical holding element is embodied as a flange arrangement and the holding element fitting is embodied as a recess arrangement. The recess of the recess means extends firstly, with respect to the orientation in the inserted state, axially, thereby acting as a key element for the flange means, in particular serving as a key fitting. These grooves then extend perpendicularly to the axis or slightly obliquely perpendicularly to the axis, wherein the groove means regions extending perpendicularly or slightly obliquely perpendicularly to the axis are caught behind the flange means by the effect of the plug-in connection, so that the cable plug-in connector is prevented from being pulled out axially.
In a further embodiment, the holding element is arranged in a manner and is provided with an oblique course (viewed obliquely with respect to a plane perpendicular to the insertion direction of the cable connector) in such a way that by actuating the first part of the locking mechanism and upon actuating this first part the holding element fitting is moved along this oblique course until it hits the rotational stop. This stop is provided on the second part of the plug-in connector and causes the cable plug-in connector to reach a terminal insertion position in the plug-in connector in which the cable plug-in connector is eventually prevented from further rotational movement in the screwing-in rotational direction and axial movement in the cable plug-in connector extracting direction.
In another embodiment, the second part has mechanical key fittings adapted to co-act with key elements of the cable plug connector with which the key fittings are fitted in such a way that the cable plug connector can only be plugged into the embedded plug connector with a specific rotational orientation preset by the key fittings.
In a further embodiment, the plug-in connector has a cover for the opening fixedly arranged on the second part flange, wherein the cover can be opened and closed by means of a pivot joint and has a sealing assembly in such a way that this sealing assembly seals the opening when the cover is in the closed state.
According to a further aspect, alone or in combination with one of the other aspects, the plug-in connector has, in addition to the basic structure described at the outset, a mechanical holding element which is adapted to prevent an axial displacement of the cable-plug-connector-side holding-element counterpart in the cable-plug-connector withdrawal direction within the frame of the first part of a latching mechanism which can be actuated by a rotation of the cable-plug connector in the screwing-in direction in a state in which the cable-plug connector is at least partially inserted into the plug-in connector. The plug-in connector is for example constructed in that the mechanical holding element is part of a bayonet lock of the cable plug-in connector and the plug-in connector. The plug-in connector further has a mechanical closing element which is adapted to cause a latch of the cable-in connector, which is connected to the latch slide, to snap into this closing element in a frame of a second part of the latching mechanism which can be actuated by moving the latch slide on the cable-in connector side, so that the cable-in connector is prevented from rotating in a unscrewing direction opposite to the screwing-in direction. This mechanical closing element is for example configured as a recess/latch receptacle for receiving a latch of the cable plug connector, so that the cable plug connector is prevented from unscrewing from a bayonet lock of the snap-in plug connector when the latch is received/snapped into the snapped-in position. This locking mechanism is implemented, for example, in the manner described in EP 3 514 892 B1.
The embedded plug-in connector is implemented in at least two parts with a first part and a second part, wherein the two parts are adapted to be directly fixed to a mounting plate. For direct attachment to the mounting plate, the first part has a first part flange for placement onto the back side of the mounting plate and the second part has a second part flange for placement onto the front side of the mounting plate. Furthermore, the first part has a mechanical holding element and the second part has a mechanical closing element.
Another advantage of the two-part form according to this aspect is that the mounting depth of the embedded plug-in connector on the rear side of the mounting plate can be flexibly designed. As mentioned at the outset, a further development of the plug-in connector is advantageous in that it is compatible with conventional cable plug-in connectors. Conventional cable plug connectors have a manoeuvrable lock bolt which snaps into a recess/lock bolt receptacle preset on the plug-in connector side when the cable plug connector is used to penetrate a preset penetration depth into the conventional plug-in connector.
The installation depth, i.e. the extent of the embedded plug-in connector on the rear side of the mounting plate perpendicular to the mounting plate, can be reduced compared to the prior art by the two-part construction without any adjustment on the cable plug-in connector side, and this installation depth can be kept unchanged, for example, independently of the thickness of the mounting plate. As mentioned at the outset, the plug-in connector can be configured, for example, in such a way that the cross section required for the plug-in connection for the cable plug-in connector is limited only by the mounting plate recess (for example also based on the support enclosure region as described at the outset). This allows the desired mounting depth to be selected by the thickness of the second portion to be placed on the front face of the mounting plate (the extent perpendicular to the mounting plate). Because the cable-plug connector is substantially freely mated through the opening provided by the mounting plate recess (and is for example sufficiently supported by the support enclosure region as initially described), the skin depth can be freely selected, wherein the thickness of the second portion is selected in such a way that the steerable latch of the conventional cable-plug connector is arranged at the correct distance from the recess/latch receptacle of the second portion and can thus snap into this recess/latch receptacle.
The two-part form thus allows for increased flexibility to adapt to different thicknesses of the mounting plate, especially when the space adjustment between the mounting plate and another device element on the back side of the mounting plate is narrow. This may occur, for example, when the embedded plug-in connector is to be directly connected (e.g., soldered) to the printed circuit board on the back side of the mounting board.
In one embodiment, the first part has signal transmission contact elements adapted to make contact with cable-plug connector-side signal transmission contact element fittings by making a plug-in connection, thereby making signal transmission across this plug-in connection.
In a further embodiment, the second part has a support enclosure region adapted to provide a support effect for the cable plug-in connector with respect to a load force acting on the cable plug-in connector perpendicular to the direction of insertion of the cable plug-in connector in a state created by the implementation of the plug-in connection, wherein the support force of the support enclosure region counteracting the load force is carried at least partially by the mounting plate in a state of the second part mounted on the mounting plate by means of fixing the second part directly to the mounting plate in a preset manner.
In another embodiment, the second part has mechanical key fittings adapted to co-act with key elements of the cable plug connector with which the key fittings are fitted in such a way that the cable plug connector can only be plugged into the embedded plug connector with a specific rotational orientation preset by the key fittings.
In a further embodiment, the plug-in connector has a cover for the opening, which is fixedly arranged on the second partial flange, wherein the cover can be opened and closed by means of a pivot joint and has a sealing assembly in such a way that this sealing assembly sealingly closes the opening in the closed state of the cover.
According to a further aspect, alone or in combination with one of the other aspects, the embedded plug connector has, in addition to the basic structure described at the outset, a signal transmission contact element which is adapted to effect signal transmission across the plug connection by effecting contact of the plug connection with a cable plug connector-side signal transmission contact element mating piece. The plug-in connector also has mechanical key fittings which are adapted to co-act with key elements of the cable plug-in connector which cooperate with the key fittings in such a way that the cable plug-in connector can only be plugged into the plug-in connector with a specific rotational orientation which is preset by the key fittings.
These key fittings are, for example, embodied as grooves or ribs, which, due to the non-rotationally symmetrical mutual arrangement and/or due to different geometries (for example, shapes or dimensions which differ from one another), require a specific insertion direction of the cable plug connector. The key fittings are, for example, constructed as key slots that allow the insertion of the cable plug connector into the opening when the flanges of the cable plug connector are mated in shape and orientation with the key slots. Alternatively, the key fittings are constructed as flanges that allow the cable plug connector to be inserted into the opening when the key ways of the cable plug connector are matched in shape and orientation to the flanges.
These key fittings are for example constructed as flanges of different widths, wherein in this case the cable-insert connector-side key elements are constructed as guide grooves/rails/grooves of different widths. Alternatively, these key fittings are embodied, for example, as guide grooves/rails/grooves of different widths, wherein in this case the cable-plug connector-side key elements are embodied as flanges of different widths.
The embedded plug-in connector is implemented in at least two parts with a first part and a second part, wherein the two parts are adapted to be directly fixed to a mounting plate. For direct attachment to the mounting plate, the first part has a first part flange for placement onto the back side of the mounting plate and the second part has a second part flange for placement onto the front side of the mounting plate. Furthermore, the first part has signal transmission contact elements and the second part has key fittings.
By the two-part form and the arrangement of the key fitting in the second part adapted to be mounted on the front face of the mounting plate, manufacturing tolerances for the key fitting can be reduced, for example. This prevents the key element mating member from being worn out by frequent disassembly and plugging of the embedded plug connector with the cable plug connector.
In the prior art, the embedded plug-in connectors are manufactured, for example, by means of an injection molding process. In order to optimize the separation of the molding part from the injection molding material for the injection molding process, this molding part has a so-called draft angle, for example, of 0.5 ° to 1 °. This prevents, for example, sticking during the pulling out of the molded part, so that damage or warping of the injection mold produced is prevented. In conventional plug-in connectors, the injection molding process generally forces the molded part to peel in a direction in which the cable plug-in connector can be guided onto the plug-in connector (in the installed state, the peeling direction corresponds to the direction away from the mounting plate on the front side of the mounting plate). This stripping direction of the molded parts is such that in the mounted state of the plug-in mounted on the mounting plate, the key fittings are directed outwards (away from the mounting plate) only on the basis of the manufacturing process, i.e. have their maximum extent at the first contacts of the key elements mating with these key fittings of the cable plug connector. Thus, to ensure full insertion of the cable-insert connector, in the insertion region, the key fittings are larger than the size required to accommodate the key elements of the cable-insert connector. This can cause wear on the key mating members of the embedded plug connector when the cable plug connector is frequently plugged and unplugged.
By virtue of the two-part form, the first part and the second part can be manufactured in separate injection molding processes, wherein the second part, which has a key fitting and is adapted to be mounted on the front side of the mounting plate, can be manufactured in such a way that the molded part to be used in the manufacturing process can be peeled off in a direction corresponding to the direction in which the front side of the mounting plate points towards this mounting plate in the mounted state. Thus, the key fittings of the embedded plug-in connector (second portion of the embedded plug-in connector) can have their minimum extension at the first contacts of the key elements of the cable plug-in connector mating with these key fittings and can fit the dimensions of the key elements of the cable plug-in connector exactly. The wear of the key element mating element due to the frequent removal and insertion of the embedded plug connector to the cable plug connector is reduced by this exact mating.
In one embodiment, the plug-in connector has a cover for the opening, which is fixedly arranged on the second partial flange, wherein the cover can be opened and closed by means of a pivot joint and has a sealing assembly in such a way that this sealing assembly sealingly closes the opening in the closed state of the cover.
In another embodiment, the thickness of the sheath element of the embedded plug connector perpendicular to the insertion direction is less than 0.35mm. This sheath element (the outermost side wall portion of the embedded plug connector adjoining the inner side of the mounting plate recess) is adapted to extend into or through the mounting plate recess in a state mounted on the mounting plate by means of the first and second portions, so that the inner region (perpendicular to the insertion direction) of the plug is separated from the inner wall of the mounting plate recess by the sheath element (towards the insertion axis) in this case.
The embedded plug-in connector has no sheathing element covering the cable plug-in connector at the level of the mounting plate recess, in particular in the state of being fixed on the mounting plate, so that this embedded plug-in connector is configured in such a way that the smallest mounting plate recess size is limited only by the cable plug-in connector.
In another embodiment, the first part flange has blind holes adapted to be mounted on a mounting plate, wherein each of the blind holes is adapted to receive a fixing member, such as a screw or pin, from the mounting plate for fixing the first part flange to the mounting plate.
In a further embodiment, the first partial flange and/or the second partial flange has a sealing element surrounding the opening, which is adapted to produce a sealing effect by pressing onto the mounting plate when the plug-in connector is placed on this mounting plate.
The sealing element is formed, for example, integrally with the first part flange or the second part flange, for example, in that the sealing element is produced by means of 2-component or multicomponent injection molding.
According to a further aspect, alone or in combination with one of the other aspects, the embedded plug connector has, in addition to the basic structure described at the outset, a signal transmission contact element which is adapted to effect signal transmission across the plug connection by effecting contact of the plug connection with a cable plug connector-side signal transmission contact element mating piece. The plug-in connector also has mechanical locking elements which are adapted to, within the frame of the locking mechanism, cause the locking elements to interact with the locking of the cable-plug-connector-side locking-mechanism counterpart element in such a way by actuating the cable-plug-connector-side locking slider, so that the cable plug connector in the inserted state locked in the plug-in connector is prevented from rotating and axially moving in the cable-plug-connector removal direction. These locking elements form, for example, a bayonet connection for locking the cable plug connector in the plug-in connector, wherein this plug-in connector has a latch socket for receiving a latch of the cable plug connector, so that, when the latch is received/snapped into the snapped-in position, a unscrewing movement of the cable plug connector from the bayonet locking of the plug-in connector is prevented.
Furthermore, the plug-in connector is suitable for being directly fastened to the mounting plate at least by means of a part or the whole of the plug-in connector having a flange for placement on the front side of the mounting plate. The plug-in connector has a cover for the opening, which is fixedly arranged on the flange, which can be opened and closed by means of a pivot joint and has a sealing assembly in such a way that the sealing assembly sealingly closes the opening in the closed state of the cover.
This cover is for example constructed as a resilient sealing cover which closes automatically after the cable plug connector has been pulled out, thereby ensuring that dust and water protection is achieved immediately, for example in accordance with protection class IP65.
A top cover as known in the art is typically mounted as another accessory to the embedded plug-in connection. The pivot joint is constructed in a resilient manner such that the top cover moves itself to the closed position, for which purpose the spring is wound around the pivot joint. Because these attachments are not already co-designed with the flange, the space available for the spring is usually small. In this way, the spring, which has only a relatively small number of turns, has an excessive torque felt by the user in the fully open state (in order to insert or extract the cable-plug connector, for example) for properly holding the top cover open. In the closed state, this torque must be at a minimum for sealingly closing the cover, and then increases in a jump due to the spring characteristics when opening the cover.
By mounting the cover directly on the flange, the probability of incorrect mounting can be reduced and the reduction of the sealing effect associated therewith can be reduced. On the other hand, the cap and the flange can be manufactured in such a way that they cooperate with each other, so that, for example, the space required for a spring adapted to close the cap is increased. In this way, a greater pressing torque can be achieved in the closed state, while the back pressure torque can be increased more uniformly or slightly when the cover is opened.
In one embodiment, the sealing arrangement is arranged and constructed in such a way that, in the closed state of the cover, in addition to the openings, the fastening member bores and the fastening members possibly inserted therein are also hermetically closed, in particular such that this opening is in this case arranged together with these fastening member bores and the fastening members possibly inserted therein in a common sealing chamber formed by the sealing arrangement.
In a further embodiment, the pivot joint is constructed in a resilient manner such that the cover is automatically moved into the closed position, for which purpose the spring is wound around the pivot joint and extends in the direction of the pivot in the region of two-thirds, in particular three-quarters, of the extent of the second part flange.
In a further embodiment, the opening can be sealed off in a sealing manner by means of a sealing device which is brought into a sealing state by closing the cover, and which has a sealing collar and a sealing collar fitting. The sealing collar fitting is arranged, for example, on the flange around the opening, and the sealing collar is arranged on the cover. Alternatively, the sealing rail is arranged on the flange around the opening, and the sealing rail fitting is arranged on the top cover. Furthermore, the sealing bead engages with the sealing bead fitting in its shape and its dimensions in such a way that radial stresses due to elastic deformation of the sealing bead are generated across the entire circumference of the sealing bead by the sealing bead being pivoted onto the sealing bead fitting, wherein the sealing bead and the sealing bead fitting each have a curved (or meandering) course and are convex over their entire circumference.
In a further embodiment, the flange and the top cover cooperate in such a way that in the closed state of the top cover a labyrinth seal is formed which provides the first sealing stage with a throttling effect. Furthermore, the contact seal with the elastomeric seal assembly provides a second sealing stage downstream of the first sealing stage, for example, wherein this contact seal is provided by the seal rail described at the outset and the seal rail mating member described at the outset.
According to a further aspect, alone or in combination with one of the other aspects, the embedded plug connector has, in addition to the basic structure described at the outset, a signal transmission contact element which is adapted to effect signal transmission across the plug connection by effecting contact of the plug connection with a cable plug connector-side signal transmission contact element mating piece. The plug-in connector also has mechanical locking elements which are adapted to, within the frame of the locking mechanism, cause the locking elements to interact with the locking of the cable-plug-connector-side locking-mechanism counterpart element in such a way by actuating the cable-plug-connector-side locking slider, so that the cable plug connector in the inserted state locked in the plug-in connector is prevented from rotating and axially moving in the cable-plug-connector removal direction. The embedded plug connector has a flange for placement onto the mounting plate and a securing member aperture for securing the embedded plug connector directly to the mounting plate (via a securing member inserted into the securing member aperture).
The plug-in connector also has a cover for the opening, wherein the cover can be opened and closed by means of a pivot joint. The opening and the fastening element openings and the fastening elements possibly inserted therein can be sealed off by means of a sealing device which is brought into a sealing state by closing the cover, which sealing device has a sealing collar and a sealing collar fitting. Furthermore, the sealing bead engages with the sealing bead fitting in its shape and its dimensions in such a way that radial stresses due to elastic deformation of the sealing bead are generated across the entire circumference of the sealing bead by the sealing bead being pivoted onto the sealing bead fitting, wherein the sealing bead and the sealing bead fitting each have a curved (or meandering) course and are convex over their entire circumference.
In one embodiment, the sealing rail fitting is arranged on the flange around the opening, and the sealing rail is arranged on the cover. Alternatively, the sealing rail is arranged on the flange around the opening, and the sealing rail fitting is arranged on the top cover.
In a further embodiment, the locking mechanism element has a mechanical holding element which is adapted to prevent an axial displacement of the cable plug connector-side holding element fitting in the cable plug connector withdrawal direction within the frame of the first part of the locking mechanism, which locking mechanism can be actuated by a rotation of the cable plug connector in the screwing direction in a state in which the cable plug connector is at least partially inserted into the plug connector. The locking element furthermore has a mechanical closing element which is adapted to cause, within the frame of the second part of the locking mechanism which can be actuated by moving the cable-plug connector-side locking slide, a locking bolt of the cable-plug connector which is connected to the locking slide to snap into this closing element, so that the cable-plug connector is prevented from rotating in a unscrewing direction which is opposite to the screwing-in direction.
In another embodiment, the sealing enclosure fitting or the sealing enclosure encloses a bore hole adapted to be mounted on a mounting plate by means of a penetrating fixation member, such as a screw or pin. That is, the bores are arranged in the circumference of the sealing apron fitting or sealing apron.
In a further embodiment, the flange and the top cover cooperate in such a way that in the closed state of the top cover a labyrinth seal is formed which provides the first sealing stage with a throttling effect. Furthermore, a second sealing stage downstream of the first sealing stage is provided by the flip-over of the sealing rail onto the sealing rail fitting.
According to a further aspect, alone or in combination with one of the other aspects, the embedded plug connector has, in addition to the basic structure described at the outset, a signal transmission contact element which is adapted to effect signal transmission across the plug connection by effecting contact of the plug connection with a cable plug connector-side signal transmission contact element mating piece. The plug-in connector also has mechanical locking elements which are adapted to, within the frame of the locking mechanism, cause the locking elements to interact with the locking of the cable-plug-connector-side locking-mechanism counterpart element in such a way by actuating the cable-plug-connector-side locking slider, so that the cable plug connector in the inserted state locked in the plug-in connector is prevented from rotating and axially moving in the cable-plug-connector removal direction. The plug-in connector is suitable for being directly fixed on a mounting plate and has a flange for being placed on the mounting plate.
The plug-in connector has a cover for the opening, wherein the cover can be opened and closed by means of a pivot joint. This opening can be sealed off by means of a sealing device which is brought into a sealing state by closing the top cover, for which purpose the flange and the top cover cooperate in a manner such that a labyrinth seal is formed which provides the first sealing stage with a throttling effect. Further, a contact seal is provided having an elastomeric seal dam and a seal dam mating member, wherein the seal dam is mated with the seal dam mating member in a manner in its shape and its dimensions to create a stress on the seal dam mating member by the seal dam being flipped over across the seal dam mating member due to elastic deformation of the seal dam.
In one embodiment, the flange and the cover cooperate in such a way that in the closed state of the cover, a cover element, for example an edge element of this cover, arranged around the opening rests against the cover element bearing surface of the flange. The flange has a projection on the inner side (toward the opening) of the top cover element bearing surface, which projection extends axially in the direction of withdrawal of the cable plug-in connector, so that by abutting the top cover element against the top cover element bearing surface, this projection projects into the top cover, thereby providing a part of the labyrinth seal.
The flange has, for example, a plurality of stepped projections rising toward the opening, and the cover has cover elements (smaller extension toward the axis) which cooperate with the projections and are adapted to rest on the stepped projections, which in the closed state of the cover have different extensions in an axially stepped manner. By closing the cover, cover elements having different extensions are fittingly abutted against these stepped projections, thereby providing a plurality of labyrinth elements of the labyrinth seal.
In a further embodiment, the sealing flap fitting is constructed as a further projection which is arranged on the inner side of the projection and extends axially (in the direction of the removal of the cable plug connector) and which is adapted to be sealed against the flap when the cover is closed.
In a further embodiment, the cover is constructed in such a way that, in the open state of the cover and in the inserted state of the cable plug-in connector, which is entered by making a plug-in connection, the element of the cover which is harder than the sealing surround (not constructed as an elastomer) rests against the cable plug-in connector. This element of the cap is, for example, a cap element (e.g. an edge element of the cap) adapted to provide a labyrinth seal, in which case this cap abuts against the cable plug connector, in particular at the location of the cap-side assembly of the labyrinth seal.
In one exemplary embodiment of the power supply plug-in connector, the invention relates to a plug-in connector for precisely mating with a mechanically lockable plug-in connection of a cable plug-in connector which is mated as a mating element with the plug-in connector and can be inserted into an opening of the plug-in connector. The conduction of the power signal from the embedded plug-in connection towards the cable plug-in connection is achieved by the plug-in connection being achieved between the embedded plug-in connector and the cable plug-in connector. The embedded plug-in connector is adapted to be secured to the mounting plate and to be fixedly carried by the mounting plate in a mounted state on the mounting plate.
The mounting plate has a mounting plate recess for the embedded plug connector and/or the cable plug connector, the embedded plug connector being adapted to be placed and supported on an area of the mounting plate surrounding the mounting plate recess. The mounting plate has a front face, which faces somewhere, from where the cable plug connector can be guided onto the embedded plug connector in a mounted state on the mounting plate, and the mounting plate has a rear face facing in the opposite direction.
The embedded plug connector has signal line contact elements adapted to make contact with a cable plug connector side signal line contact element mating member by making a plug connection, thereby enabling transmission of power signals across this plug connection. Furthermore, the embedded plug-in connector has a supporting enclosure region adapted to provide a supporting effect for the cable plug-in connector with respect to a load force acting on the cable plug-in connector perpendicular to the insertion direction of the cable plug-in connector in a state generated by the implementation of the plug-in connection. Furthermore, a mechanical closing element embodied as a locking element is provided, in order to cause the locking element of the cable connector, which is connected to the locking slide, to be snapped into this closing element (and thus prevent the cable connector from rotating in a unscrewing direction opposite to the screwing-in direction) by moving the cable connector-side locking slide into the frame of the locking mechanism, which can be actuated in the state in which the cable connector is axially inserted into the plug-in connector.
The embedded plug-in connector is implemented in at least two parts with a first part and a second part, wherein the two parts are adapted to be directly fixed to a mounting plate. To this end, the first part has a first part flange for placement onto the back side of the mounting plate and the second part has a second part flange for placement onto the front side of the mounting plate. The first part has a signal transmission contact element and the second part has a support enclosure region, wherein the support force, which counteracts the load force exerted by the support enclosure region, is at least partially carried by the mounting plate in the mounted state of the second part by means of the direct fastening of the second part to the mounting plate in a predetermined manner. Furthermore, the second part has a mechanical closing element.
In the secured state on the mounting plate, the embedded plug connector has no sheathing element covering the cable plug connector at the level of the mounting plate recess, so that this embedded plug connector is configured in such a way that the smallest mounting plate recess size is limited only by the cable plug connector.
In one embodiment, the first part flange has blind holes adapted to be mounted on a mounting plate, wherein each of the blind holes is adapted to receive a fixing member, such as a screw or pin, from the mounting plate for fixing the first part flange to the mounting plate.
In a further embodiment, the first partial flange and/or the second partial flange has a sealing element surrounding the opening, which is adapted to produce a sealing effect by pressing onto the mounting plate when the plug-in connector is placed on this mounting plate.
This sealing element is produced, for example, by means of 2-component or multicomponent injection molding and is integrally formed with the first part flange or the second part flange.
For an embodiment based on the aspects described at the outset: the embedded plug-in connector is constructed in at least two-part fashion and has a first part and a second part adapted to be fixed directly to the mounting plate, the second part adapted to be mounted on the front side of the mounting plate may for example be made of metal. The first part, which is suitable for mounting on the rear side of the mounting plate, preferably has or is in particular made of an insulating material.
The advantage of the solution in which the second part is made of metal is, for example, that it wears slower (e.g. compared to softer, in particular electrically insulating materials, such as plastics), and therefore the second part is suitable for use in particularly harsh environments. Such a second part made of metal can be used for example for equipment that is to be leased and therefore often to be installed and removed (and possibly handled less carefully). The use of metal, for example, further reduces the wear of the key element mating pieces (or in general the regions/elements of the embedded plug connector forming the insertion openings for the cable plug connector) arranged on the second part, which is caused by frequent disassembly and plugging of the embedded plug connector with the cable plug connector.
Furthermore, the present invention relates to the embedded plug-in connector of the above embodiments, however, in these embodiments all aspects relating to the two-part form are implemented in other embodiments in such a way that the second part is an integral part of the mounting plate. In this case, in one embodiment, this second part is also made of metal, for example, in order to reduce wear.
The aspects described above with respect to the cap and the labyrinth seal and contact seal (provided by the cap element) may be implemented independently of the two-part version of the embedded plug connector.

Detailed Description
Aspects of the present invention are illustratively shown in connection with two different embodiments of a current signal output embedded plug-in connector (fig. 1A-1D, 11A-11D) and a current signal input embedded plug-in connector (fig. 3A-3D, 12A-12D) suitable for use in a power supply. Compared with the known power plug, the embedded plug-in connector of the invention has the following advantages: the design of the current output embedded plug-in connector for other widely used types of drilling and installation dimensions for the embedded plug-in connector can be achieved. The embedded plug-in connector is constructed, for example, according to the so-called D-size (see fig. 18A-18B, fig. 21).
Based on the large number of cable plug connectors and embedded plug connectors that circulate around the world, further developments in embedded plug connectors are economical in that they are compatible with conventional cable plug connectors provided as mating members for mating with embedded plug connectors (see fig. 22A-22E and fig. 26A-26E). In addition to electrical or optical signal transmission compatibility, well-defined mechanical boundary conditions are also to be met.
Conventional plug-in connectors are, for example, configured for so-called bayonet locks, for which purpose they have guide means which interact with key elements of the cable plug-in connector which cooperate with the guide means and with the guide means cooperation in such a way that the cable plug-in connector can only be plugged into the plug-in connector by means of a specific rotational orientation preset for the key elements and can be plugged into the opening axially deeper by means of a rotational movement about the plug-in axis (see, for example, fig. 5A to 5B, which show a plug-in connector according to the invention with a recess or flange constructed as a key cooperation). At a predetermined penetration depth, a locking position is reached in which the cable-plug-connector-side retaining element fitting engages behind the retaining element of the plug-in connector, so that the cable-plug connector is locked with respect to an axial movement in the cable-plug-connector removal direction. Furthermore, the cable-plug connector is prevented from rotating by means of the latch of the cable-plug connector which engages in the latch socket of the plug-in connector. Furthermore, the key elements, guide fittings, retaining element fittings and latches of the cable plug connector must also be sized and positioned to be compatible with the further developed drop-in plug connectors.
The embedded plug-in connector according to the invention may be configured for different applications, for example for signal transmission of power signals or for transmission of audio signals. Depending on the application, the cable plug-in connector (for example, according to the prior art) which cooperates therewith is used as a mating element for the exact-fit realization of the mechanically lockable plug-in connection with the plug-in connector according to the invention, in particular in that the respective cable plug-in connector can be inserted into the exact-fit opening of the plug-in connector. By realizing the plug-in connection, the signal transmission contact element of the embedded plug-in connector is contacted with the signal transmission contact element mating piece on the cable plug-in connector side, so that signal transmission crossing the plug-in connection is realized.
The mounting plate has a mounting plate recess for the embedded plug connector and/or the cable plug connector, wherein the embedded plug connector is adapted to be placed and supported on an area of the mounting plate surrounding the mounting plate recess. Hereinafter, the front side of the mounting plate refers to the area facing somewhere from where the cable plug connector (in the mounted state of the embedded plug connector) can be guided onto the embedded plug connector. The opposite side of the mounting plate is referred to as the back side of the mounting plate.
Within the present invention, the "mounting plate" may have different shapes. The mounting plate is, for example, a planar two-dimensional plate or a planar device component on a device (e.g., a speaker) adapted to mount an embedded plug-in connector. The mounting plate may also consist of a part of the housing of the device, for example. In particular, in the case of a mounting plate provided by a device component (for example a headlight or a loudspeaker), the mounting plate can also have a curved (non-planar) shape in a special design. In this case, the embedded plug connector can accordingly have a form-fitting bore or a fastening arrangement with the mounting plate.
According to one aspect of the invention, the embedded plug-in connector is of a two-part design and has a first part and a second part, which are adapted to be directly secured to the mounting plate. For fixation, the first part has a first part flange for placement on the back side of the mounting plate and the second part has a second part flange for placement on the front side of the mounting plate (see fig. 2A-2C and fig. 4A-4C). The first and second partial flanges have, for example, blind holes adapted to be mounted on a mounting plate, wherein each of these blind holes is adapted to receive a fixing member, such as a screw or pin, from the mounting plate.
The advantage of the two-part form and the direct mounting of the second part on the mounting plate is, for example, that the second part can take on a considerable supporting component by means of the supporting enclosure region (or transfer it directly to the mounting plate) in order to protect the embedded plug-in connector from the loading forces acting on the cable plug-in connector perpendicular to the direction of insertion of the cable plug-in connector in the event of insertion (or at least partial insertion) of the cable plug-in connector.
Furthermore, the two-part form makes better use of the possible space requirements for the opening, which is limited by the prior art fixing of the drilling and mounting dimensions on the predetermined mounting plate. Thus, for example, the jacket wall passing through the mounting plate recess can be omitted, so that the cross section provided for the plug-in connection for the cable plug-in connector is limited only by the mounting plate recess (and not by the elements of the embedded plug-in connector).
With the prior art integrally formed plug-in connectors, such a sheathing wall, i.e. the outermost side wall portion which in the mounted state on the mounting plate protrudes into the mounting plate recess in such a way that it adjoins the inner wall of the mounting plate, is generally used in order to exert a supporting effect, for example with respect to load forces transverse to the insertion direction, or to provide a latching socket on the front side of the mounting plate in order to prevent a bayonet lock. According to the invention, these functions can be taken over by the second part, the support enclosure region described in the opening paragraph enhancing the support effect.
Thus, a current output embedded plug suitable for use in a power supply may be provided for installation with the drilling and installation dimensions of a more widely used power input plug and audio plug. Heretofore, the power supply embedded plug-in connectors configured for signal output have been larger in drilled and installed size than power supply embedded plug-in connectors suitable for signal input (see, for example, fig. 18A-18B, 19A-19B). As a result of the innovative two-part form, the power output plug can be adapted to the dimensions of other embedded plug connectors, so as to meet the strict specifications regarding the globally universal installation dimensions of other plugs, which are usually manufactured, for example, in the so-called D-size.
Another advantage of the two-part version is that there is an increased flexibility in the depth of installation of the embedded plug connector, i.e. the extent of the embedded plug connector perpendicular to the mounting plate at the back of the mounting plate is increased (see fig. 20A-20B). The possible limit of selecting the skin depth is increased because, for example, the cross section to be provided for the plug-in connection of the cable plug-in connector is limited only by the mounting plate recess and the supporting effect is increased by the supporting enclosure region. In this case, a proper choice of the thickness of the second portion (in the insertion direction) and a corresponding positioning of the latch socket ensures that the steerable latch of a conventional cable plug is arranged at the correct distance from the recess/latch socket and can thus be snapped into this recess/latch socket.
In the prior art, the skin depth plays a role, for example, in the case of an embedded plug-in connector which is to be connected directly to a printed circuit board. In this case, a connection of the plug-in connector to the printed circuit board, which is usually not possible to be released without damage, is first established, for example by soldering. The embedded plug connector can then only be mounted to the mounting board from the back side of the mounting board. With the prior art integrally formed plug-in connectors, the mounting depth is increased in a complementary manner by the rear mounting, since the position of the flange is fixed (see fig. 20A-20B for comparing the mounting depth of prior art current signal output plug-ins for power supplies when mounted on the front and rear sides). This results, for example, in the inability to mount current signal output plug-in connectors known in the art to a printed circuit board. By providing a reduced or adaptable mounting depth with the embedded plug connector of the present invention, the current signal output plug can be moved to the same mounting depth as all other chassis plugs meeting this criteria.
Another advantage, in particular for the application of the embedded plug-in connector to a printed circuit board, is that, for example, in the event of damage to the embedded plug-in connector, a better exchange is possible. In the prior art, in order to separate the entire plug from the printed circuit board, it is often necessary to open the entire housing of the device in which the embedded plug-in connector is mounted, for example (since conventional embedded plug-in connectors are integrally formed). This generally requires high outlay and cannot be achieved in a lossless manner. Furthermore, the only embedded plug connector components on the plug-in side that are damaged tend to be damaged, since they are directly exposed to external influences and mainly provide plug-in and plug-out functions. Repeated (i.e. frequent) insertion processes (i.e. insertion into or extraction from the cable plug-in connector) can lead to wear of the plug-in connector, wherein in this case the wear is manifested exactly at and around the insertion opening of the plug-in connector. Thanks to the two-part design of the embedded plug-in connector according to the invention, unlike SdT, only the second part of the plug-in connector (which is pressed and exposed to wear) can be replaced individually/independently with low effort (and without opening the device in which the embedded plug-in connector is installed, for example), while the unused first part can be used further.
Furthermore, even in the case of an embedded plug-in connector mounted on the bottom side of a printed circuit board, the two-part form can be used, for example, to seal the opening using the top cover described in the opening paragraph. This is not possible with conventional (integrally formed) plug-in connectors, since in the case of mounting/soldering on a printed circuit board (since this must be done before mounting on a mounting bag), the plug-in connector must be mounted from behind on the mounting board (flange, more not capped flange, cannot be drilled through the mounting board for design reasons).
Furthermore, it is apparent from the general relevance of the present disclosure and the technical principle presented here that the two-part design according to the invention of an embedded plug-in connector with a first and a second part means that the two parts (i.e. the two-part structure) are related to the ready-to-install state of the embedded plug-in connector. Of course, the two parts (and similarly the integral form of the SdT) of the embedded plug connector according to the invention are "internal" made up of a plurality of elements (single components or single parts) that are connected and combined together during the manufacturing process. However, the two parts of the embedded plug-in connector according to the invention form two physically separate units/complexes (i.e. can be said to be two physical, separate pieces which are not connected to each other before being mounted on the mounting board) in a state suitable for being fixed on the mounting board, i.e. in a state suitable for being embedded in a corresponding device, such as an audio/video device, e.g. a large active speaker system/active floor-mounted speaker (dedicated to theatres or concert halls). The two physical units/complexes (i.e. the two parts) of the embedded plug-in connector according to the invention are finally connected to one another (by means of the mounting plate) only after being embedded in the terminal device and in particular only by means of detachable fastening means (screw connections) here.
Furthermore, the two-part form enables smaller manufacturing tolerances of the key element mating pieces arranged on the second part, thereby reducing wear of the key element mating pieces due to frequent disassembly and plugging of the embedded plug connector with the cable plug connector.
The second part, which is suitable for being placed on the front side, can be produced in a separate injection molding process, by which the molded part for producing the key element mating part can be peeled off in a direction corresponding to the direction directed toward the mounting plate in the mounted state of the embedded plug-in connector. Thereby, the key element mating pieces may have their minimum extension at the first contact points of the key elements mating with these key element mating pieces of the cable plug connector and may fit the size of the key elements of the cable plug connector with a precise fit. The key element mating piece is prevented from being worn out due to frequent disassembly and plugging of the embedded plug-in connector and the cable plug-in connector. Furthermore, if the second part is made of metal (- > entirely of metal or at least at the region/element of the second part of the embedded plug connector forming the insertion opening for the cable plug connector), for example, wear may be further reduced or the wear rate may be reduced.
According to another aspect of the invention, the embedded plug connector is adapted to be placed at least partly or entirely by means of a flange onto the front side of the mounting plate, wherein a fixedly arranged top cover for the opening is arranged on this flange (see e.g. fig. 11A-11D and fig. 12A-12D). The cap is resiliently constructed in a manner such that it moves itself to the closed position by means of a pivot joint, wherein the cap has a sealing assembly in a manner such that the sealing assembly seals the opening when the cap is in the closed state. This sealing assembly is suitable for example for sealing according to IP65 or IP 67. This seal assembly is in particular by means of a labyrinth seal (see aspects described below) and incorporates a seal enclosure to form a seal enclosure fitting (see aspects described below).
The cover has, for example, a spring which is wound around the pivot axis of the pivot joint, wherein the cover and the flange cooperate with one another in such a way that the spring extends in the direction of the pivot axis over at least two-thirds of the extent of the flange. By increasing the extension of the spring, the number of turns of the spring can be increased. In this way, a greater pressing torque can be achieved in the closed state, while the back pressure torque can be increased more uniformly or slightly when the cover is opened.
According to a further aspect of the invention, the plug-in connector also has a cover for the opening, for example of the type described in the opening paragraph, wherein this cover has sealing means comprising a sealing collar and a sealing collar fitting (see, for example, fig. 11A-11D, fig. 12A-12D and fig. 30). The sealing rail fitting is arranged, for example, on a flange around the opening, and the sealing rail is arranged on the top cover. Alternatively, the sealing rail is arranged on the flange around the opening, and the sealing rail fitting is arranged on the top cover. When closing this top cover, the sealing rail is turned over onto the sealing rail mating part in such a way that radial stresses are generated across the entire circumference of the sealing rail due to elastic deformation of the sealing rail. This achieves a sealed closure. In order to ensure that stress is maintained over the entire circumference of the sealing bead in order to further prevent undesired leaktightness, the sealing bead and the sealing bead fitting each have a curved course and are convex over their entire circumference. Furthermore, the sealing rail and the sealing rail mating part are also shaped in such a way that they do not have straight sections.
According to a further aspect of the invention, the insert connector also has a top cover for the opening, for example of the type described in the opening paragraph, wherein the flange and the top cover cooperate in a manner such that a labyrinth seal is formed which provides the first sealing stage with a throttling effect (see, for example, fig. 11A-11D, fig. 12A-12D and fig. 31). In addition, the drop-in plug connector also has a contact seal comprising an elastomeric seal rail and a seal rail mating member, wherein this seal rail mates with the seal rail mating member in its shape and size, thereby creating a stress on the seal rail mating member across the seal rail mating member due to elastic deformation of the seal rail by flipping the seal rail over (see, e.g., fig. 11A-11D, 12A-12D, and 30).
The splash water is prevented from directly striking the elastomeric sealing enclosure when the top cover is closed, for example by a labyrinth seal. Such a labyrinth may not be sealing itself, but it reduces the energy of the water striking the sealing enclosure so that the sealing enclosure is not lifted by splash water.
The cover is, for example, constructed in such a way that in the inserted state of the cable plug connector (and thus in the open state of the cover) a comparatively stiff element of this cover (not constructed as an elastomer) is placed against the cable plug connector (see fig. 28A-28B). The hard element of this cap is, for example, a cap-side part of a labyrinth seal. Thus, the elastomeric sealing rail does not directly rest against the cable plug connector (and is not pressed against the cable plug connector and deformed by the spring action). This prevents the elastomeric seal from being damaged.
Fig. 1 is a perspective view (fig. 1A) of an exemplary embodiment of a current signal output embedded plug connector mounted on a mounting board 1 according to the present invention from the back of the mounting board, from the front of the mounting board (fig. 1B), from the side view (fig. 1C), and from the front of the mounting board (fig. 1D).
The embedded plug-in connector adopts a two-part design scheme. The first part 2 has a first part flange 3 for placement onto the back of the mounting plate 1 and the second part 4 has a second part flange 5 for placement onto the front of the large mounting plate 1. The partial flanges 3, 5 have bores for mounting to a mounting plate, wherein in the embodiment shown the partial flanges are screwed to one another by means of screws 6. For this purpose, the first part flange 3 has blind holes 7 in order to accommodate screws 6 from the mounting plate.
The second part 4 also has a supporting enclosure region 8 which provides a supporting effect for a cable plug-in connector inserted into the plug-in connector with respect to a load force acting on the cable plug-in connector perpendicular to the axial direction (perpendicular to the direction of insertion of the cable plug-in connector). By fixing the second part 4 directly to the mounting plate 1, the supporting forces counteracting the load forces exerted by the supporting enclosure area 8 are at least partly carried by the mounting plate 1.
The first part 2 has a retaining element 9 embodied as a flange which, in the inserted state, is caught behind by a groove on the cable connector side in the frame of the locking mechanism, so that the cable connector is prevented from being pulled out axially. The retaining elements 9 embodied as flanges furthermore serve as key fittings 10 which interact with key elements of the cable plug connector which cooperate with these key fittings in such a way that the cable plug connector can only be plugged into the plug connector with a specific rotational orientation preset for the key fittings 10.
The second part 4 also has a latch socket 11 adapted to engage with a latch of the cable plug connector within the frame of the latching mechanism, in order thereby to prevent the cable plug connector from rotating in the unscrewing direction.
Fig. 2 is two different perspective views (fig. 2A, 2B) and one side view (fig. 2C) of the various portions of the current signal output embedded plug-in connector shown in fig. 1A-1D separated from each other. Furthermore, in this split view, the opening 12 of the embedded plug connector for the cable plug connector is visible. Furthermore, it can be seen that in the illustrated embodiment of the plug-in connector, the cross section to be provided for the plug-in connection of the cable-in connector, i.e. the minimum mounting plate recess size, is limited only by the cable-in connector, since the plug-in connector has no sheathing element which, in the mounted state on the mounting plate, protrudes into or through the mounting plate recess in such a way that it adjoins the inner wall of the mounting plate, so that the inner region of the plug is separated from the inner wall of the mounting plate recess by this sheathing element. In other words, the mounting plate recess for mounting the embedded plug-in connector corresponds substantially to the maximum cross section of the cable plug-in connector through which the plug-in connection is to be realized.
In this exploded view, a sealing element 13 of the first flange part 3 surrounding the opening 12 is also visible, which sealing element produces a sealing effect by pressing onto the mounting plate when the plug-in connector is placed on the mounting plate. This sealing element 13 is for example integrally formed with the first partial flange 3, wherein the combination of the sealing element 13 and the first partial flange 3 is produced by means of two-component injection molding.
Fig. 3 is a perspective view (fig. 3A) from the back of the mounting board, a perspective view (fig. 3B) from the front of the mounting board, a side view (fig. 3C), and a top view (fig. 3D) from the front of the mounting board of an exemplary embodiment of a current signal input embedded plug connector mounted on the mounting board 1 according to the present invention.
This embedded plug-in connector is of a two-part design and has a first part 2 'comprising a first part flange 3' for placement onto the rear side of the mounting plate 1 and a second part 4 'comprising a second part flange 5' for placement onto the front side of the mounting plate 1. The partial flanges 3', 5' have bores for mounting to a mounting plate, wherein the partial flanges are screwed together by means of screws 6'. For this purpose, the first partial flange 3' has blind holes 7' in order to accommodate screws 6' from the mounting plate. The second part 4' also has a supporting enclosure area 8' surrounding the opening 12' for the cable plug-in connector, which provides the supporting effect as described at the beginning for the plug-in connector shown in fig. 1.
The first part 2' has key fittings 10' which are designed as grooves, wherein these grooves extend firstly axially, so that a rotational orientation for inserting the cable plug connector into the plug-in connector is preset, then extend perpendicularly to the axis (perpendicular to the insertion direction of the cable plug connector into the plug-in connector) or slightly obliquely perpendicularly to the axis and serve as holding elements 9' in this region. In this case, the cable-plug connector-side holding element mating element or key element is embodied here as a flange arrangement, which can be inserted into the recess with the cable-plug connector oriented in a correct rotation, wherein in this case the cable-plug connector is prevented from being pulled out axially in the final position by the flange in the region of the recess extending perpendicularly to the axis or slightly obliquely perpendicularly to the axis.
The second part 4 'also has a latch socket 11', which, as described above for the plug-in connector shown in fig. 1, is adapted to engage with a latch of the cable-plug connector in the frame of the locking mechanism.
Fig. 4 is two different perspective views (fig. 4A, 4B) and one side view (fig. 4C) of the various portions of the current signal input embedded plug-in connector shown in fig. 3A-3D separated from one another. The plug-in connector also has a sealing element 13' surrounding the opening 12' of the first partial flange 3', which sealing element produces a sealing effect by pressing onto the mounting plate when the plug-in connector is placed on the mounting plate.
Fig. 5 is a perspective view of the opening 12 of the current signal output female plug connector shown in fig. 1A-1D (fig. 5A) and a perspective view of the opening of the current signal input female plug connector shown in fig. 3A-3D (fig. 5B).
In the case of the current signal output plug-in connector shown in fig. 1A to 1D, in particular four key fittings 10 or retaining assemblies 9 embodied as flanges can be seen here.
In the case of the current signal input plug-in connector shown in fig. 3A-3D, four recesses can be seen here which serve as key fittings 10 'or retaining assemblies 9'. These grooves extend axially in a first section 14, which is suitable for use as a key fitting 10', and then transition into a run perpendicular or slightly inclined to the axis in a second section 15, which is suitable for use as a retaining assembly 9'. One of these grooves serves at the same time as a latch socket 11' which is adapted to engage with the latch of the cable-entry connector in the frame of the locking mechanism.
In this view, furthermore, a signal transmission contact element 16 is also visible, which is adapted to be brought into contact with a cable plug connector-side signal transmission contact element counterpart by means of the plug-in connection.
Fig. 6 is a perspective view (fig. 6A) of the current signal output embedded connector shown in fig. 1A to 1D mounted to the mounting board 1 in such a manner as to be mounted beside the current signal input embedded connector shown in fig. 3A to 3D, from the front side of the mounting board 1, from the rear side of the mounting board (fig. 6B), and from the side view (fig. 6C).
Both plug-in connectors are constructed according to the so-called D-dimension, i.e. the side length of the respective first 3, 3 'and second 5, 5' partial flange is 26mm (flange width) x 31mm (flange length), the diameter of the mounting plate bore (mounting plate recess) is between 23.6 and 24 mm.
Fig. 7 is a perspective view of the plug-in device of fig. 6 adapted to be mounted to a mounting plate from the back side of the mounting plate 1 (fig. 7A) and from the front side of the mounting plate (fig. 7B).
In the case of two embedded plug connectors, a corresponding two-part form and a division into a corresponding first part 2, 2 'and second part 4, 4' can be seen. Since the two plug-in connectors, i.e. the current outlet plug-in connectors, can be produced in particular in D-size, a uniform mounting plate bore can be used for both plug types.
Fig. 8 is a side view of the embedded plug device of fig. 6 adapted to be mounted to a mounting plate.
Fig. 9 is a cross-sectional view of two of the embedded plug connectors shown in fig. 6 mounted to the mounting board 1. In this illustration, in particular, the compression seals 13, 13 'of the respective first partial flange 3, 3' on the mounting plate 1 can be seen. In addition, as far as the current output plug-in connector is concerned, it is clear that the first and second partial flanges 3, 5 do not have a jacket element which protrudes into the mounting plate recess, and that the extent of the openings of the first and second partial flanges 3, 5 in the cutting direction corresponds substantially to the extent of the mounting plate recess. In other words, the mounting plate recess for mounting the embedded plug-in connector corresponds substantially to the maximum cross section of the cable plug-in connector through which the plug-in connection is to be realized.
Fig. 10 is a cross-sectional view of the current signal output embedded plug connector shown in fig. 6 mounted to the mounting board 1, wherein this cross-sectional line is rotated ninety degrees relative to the cross-sectional view shown in fig. 9.
Fig. 11 is a perspective view (fig. 11A) from the back of the mounting board, a perspective view (fig. 11B) from the front of the mounting board, a side view (fig. 11C), and a top view (fig. 11D) from the front of the mounting board of another exemplary embodiment of a current signal output embedded type plug-in connector mounted on the mounting board 1 according to the present invention.
In the basic structure, this embedded plug-in connector is constructed in a manner similar to the embedded plug-in connector shown in fig. 1A-1D, i.e. in a two-part manner with a first part 2 "having a first part flange 3" for placement onto the rear side of the mounting plate 1 and a second part 4 "having a second part flange 5" for placement onto the front side of the mounting plate 1. The partial flanges 3", 5" have bores for mounting to a mounting plate, wherein the partial flanges are screwed together by means of screws 6". For this purpose, the first partial flange 3 "has blind holes 7" in order to accommodate screws 6 "from the mounting plate.
The second part 4 "also has a supporting enclosure area 8" which provides a supporting effect for a cable plug-in connector inserted into the plug-in connector with respect to a load force acting on the cable plug-in connector perpendicular to the axial direction (perpendicular to the direction of insertion of the cable plug-in connector). By fixing the second portion 4 "directly to the mounting plate 1, the supporting forces exerted by the supporting enclosure region 8" counteracting the load forces are at least partly carried by the mounting plate 1.
The first part 2″ has a retaining element 9″ embodied as a flange, which in the inserted state is caught behind by a groove on the cable connector side in the frame of the locking mechanism, so that the cable connector is prevented from being pulled out axially. Furthermore, the holding elements 9 "embodied as flanges also serve as key fittings 10", which cooperate with key elements of the cable plug-in connector, which cooperate with these key fittings, in such a way that the cable plug-in connector can only be plugged into the plug-in connector with a specific rotational orientation preset for the key fittings 10 ".
The second part 4 "also has a latch socket 11" adapted to engage with a latch of the cable-plug connector within the frame of the locking mechanism, in order thereby to prevent the cable-plug connector from rotating in the unscrewing direction.
In addition, in this embodiment, the second part 4″ also has a cover 17 for the opening, which is fixedly arranged on the second part flange 5″. This top cover is constructed resiliently in such a way by means of a pivot joint 18 that it moves itself towards the closed position.
The top cover 17 is suitable for sealing in accordance with IP65 and has for this purpose a labyrinth seal providing a first sealing stage with a throttling effect and a contact seal with an elastomer sealing assembly, which provides a sealing stage downstream of the first sealing stage.
In order to create a labyrinth seal, the cover 17 and the second partial flange 5 "cooperate in such a way that, in the closed state of the cover 17, an edge element 19 of this cover, which is arranged around the opening 12", rests against a cover edge bearing surface 20 of the second partial flange 5 ". Furthermore, the second part flange 5″ has a projection 21 on the inside of the top cover edge bearing surface 20, so that by abutting the top cover edge element 19 against the top cover edge bearing surface 20, the projection 21 protrudes into the top cover 17, thereby providing a labyrinth seal effect.
In the case of the second sealing stage, the cover 17 has an elastomer sealing rail 22 and a sealing rail fitting 23 arranged on the projection 21 (which for example simultaneously forms part of the support rail region 8 "), wherein the sealing rail 22 engages with the sealing rail fitting 23 in terms of its shape and size in such a way that a stress to the sealing rail fitting 23 by the elastic deformation of the sealing rail 22 is generated across the sealing rail fitting 23 by the flip-over of the sealing rail 22.
In the embodiment shown, the sealing apron fitting 23 or the sealing apron 22 encloses a borehole adapted to mount the second partial flange 5″ on the mounting plate 1. Thus, the bore of the second partial flange leading to the blind bore 7 "of the first partial flange is located within the circumference of the sealing bead fitting 23 or the sealing bead 22 and is thereby sealed in the same way as the opening 12".
Fig. 12 is a perspective view (fig. 12A) from the back of the mounting board, a perspective view (fig. 12B) from the front of the mounting board, a side view (fig. 12C), and a top view (fig. 12D) from the front of the mounting board of another exemplary embodiment of a current signal input embedded type plug connector mounted on the mounting board 1 according to the present invention.
This embedded plug-in connector is of a two-part design and has a first part 2 '"comprising a first part flange 3'" for placement onto the rear side of the mounting plate 1 and a second part 4 '"comprising a second part flange 5'" for placement onto the front side of the mounting plate 1. The partial flanges 3 ' ", 5 '" have bores for mounting to a mounting plate, wherein the partial flanges are screwed together by means of screws 6 ' ". For this purpose, the first partial flange 3 ' "has a blind hole 7 '" for receiving a screw 6 ' "from the mounting plate. The second part 4 ' "also has a supporting enclosure region 8 '" surrounding an opening 12 ' "for a cable plug-in connector, which provides the supporting effect as described at the outset for the plug-in connector shown in fig. 1.
The first part 2 ' "has key fittings 10 '" which are constructed as grooves which extend firstly axially so as to preset a rotational orientation for inserting the cable plug connector into the plug-in connector and then extend perpendicularly to the axis (perpendicular to the insertion direction of the cable plug connector into the plug-in connector) or slightly obliquely perpendicularly to the axis and serve as holding elements 9 ' "in this region. In this case, the cable-plug connector-side holding element mating element or key element is embodied here as a flange arrangement, which can be inserted into the recess with the cable-plug connector oriented in a correct rotation, wherein in this case the cable-plug connector is prevented from being pulled out axially in the final position by the flange in the region of the recess extending perpendicularly to the axis or slightly obliquely perpendicularly to the axis.
The second part 4 '"also has a latch socket 11'" which, as described above for the plug-in connector shown in fig. 1, is adapted to engage with a latch of the cable-plug connector within the frame of the locking mechanism.
The second part 4 ' "furthermore has a top cover 17' for the opening which is fixedly arranged on the second part flange 5 '". This cap is constructed resiliently in such a way by means of a pivot joint 18' that it moves itself towards the closed position.
The top cover 17' has a labyrinth seal as described initially for the cable plug connector in fig. 11, which provides a first sealing stage with a throttling effect, and a contact seal comprising an elastomer sealing assembly, which provides a sealing stage downstream of the first sealing stage. For this purpose, the cover 17' has an edge element 19' arranged around the opening 12 ' "which is adapted to rest on the cover edge bearing surface 20' of the second partial flange 5 '". Furthermore, the second partial flange 5 ' "has a projection 21' inside the top cover edge support surface 20', so that by abutting the top cover edge element 19' against the top cover edge support surface 20', the projection 21' protrudes into the top cover 17', thereby providing a labyrinth seal effect.
In the case of the second sealing stage, the cover 17 'has an elastomer sealing collar 22' and a sealing collar fitting 23 '(which, for example, at the same time forms part of the support collar region 8' ") arranged on the projection 21', wherein the sealing collar 22' engages the sealing collar fitting 23 'in terms of its shape and size in such a way that a stress is applied to the sealing collar fitting 23' by the sealing collar 22 'due to elastic deformation of the sealing collar 22' is generated across the sealing collar fitting 23 'by the flip-over of the sealing collar 22'.
Fig. 13 is a perspective view (fig. 13A) of the current signal output embedded connector shown in fig. 11A to 11D mounted to the mounting board 1 in such a manner as to be mounted beside the current signal input embedded connector shown in fig. 12A to 12D, from the front side of the mounting board 1, from the rear side of the mounting board (fig. 13B), and from the side view (fig. 13C).
Both plug connectors are constructed according to the so-called D-size.
Fig. 14 is a perspective view of the plug-in device of fig. 13 adapted to be mounted to a mounting plate from the front side of the mounting plate 1 (fig. 14A) and from the back side of the mounting plate (fig. 14B).
For two embedded plug connectors, a corresponding two-part form can be seen and split into a corresponding first part 2", 2 '" and second part 4", 4'". Since the two plug-in connectors, i.e. the current outlet plug-in connectors, comprise a top cover 17, 17', can in particular be made in D-size, a uniform mounting plate drilling can be used for both plug types.
Fig. 15 is a side view of the embedded plug device of fig. 13 adapted to be mounted to a mounting plate.
Fig. 16 is a cross-sectional view of two of the embedded plug connectors shown in fig. 13 mounted to the mounting board 1. In this figure, in particular, the compression seals 13", 13 '" of the respective first partial flanges 3", 3'" on the mounting plate 1 can be seen. Furthermore, in this embodiment, the respective second partial flange 5", 5 '" also has a compression seal 24, 24' (formed integrally with these flanges), which will also be highlighted again in particular in fig. 17.
Fig. 17 shows the section of fig. 16 again, but here, a cable plug connector is inserted into the current outlet plug, and the compression seals 13", 24, which are formed integrally with the flange of this current outlet plug, are highlighted.
Fig. 18 shows the layout of a prior art current signal input insert connector 25, the current signal input insert connector shown in fig. 3A-3D, the current signal output insert connector shown in fig. 1A-1D, and a prior art current signal output insert connector 26. In addition, a prior art cable plug-in connector 27 is inserted into each of the two current signal output plug-in connectors. This layout is shown on the one hand in a perspective view (fig. 18A) from the front side of the mounting plate 1 and on the other hand in a side view (fig. 18B).
The prior art current signal input plug-in connector 25 and the two plug-in connectors according to the invention each meet the so-called D-size requirement. However, the prior art current signal output embedded plug connector 26 has a larger size than this. In the prior art, the embedded plug connectors 25, 26 are integrally formed.
Fig. 19 in turn shows the arrangement of fig. 18 of the plug-in connector in two different perspective views, wherein this arrangement is supplemented by a further current signal output plug-in connector 26' of the prior art. This prior art further current signal output plug-in connector 26' adopts the same design as the prior art further current signal output plug-in connector 26, but is mounted onto the mounting board 1 from the rear side of the mounting board 1.
When the embedded plug connector is to be soldered to the printed circuit board 28, for example, a back-side mounting is required. For this purpose, the plug-in connectors are usually first soldered to the printed circuit board 28, and then can only be guided on the rear side onto a mounting board and mounted on this mounting board (prior art plug-in connectors 25, 26 are integrally formed). The back mounting increases the mounting depth (see fig. 20).
In all the current signal output plug-in connectors, a cable plug-in connector 27 of the prior art is inserted again.
Fig. 20 is two side views of the embedded plug connector and cable plug connector arrangement of fig. 19. The distance of the actual printed circuit board 28 from the mounting board 1 is generally standardized and corresponds approximately to the distance shown in the figures. In this case, this distance is too short for a smooth installation of the conventional current signal output embedded plug-in connectors 26, 26'. The plug housing is already located on the printed circuit board 28 (or has passed through it) when the embedded plug connector 26' should be mounted on the rear side to the mounting board 1 and the widely used distance between the printed circuit board 28 and the mounting board 1 is maintained. This is a known problem of prior art current signal output embedded connectors.
By means of the two-part design according to the invention of the current signal output plug-in connector, the installation depth (the extent of the plug-in connector extending from the mounting plate on the rear side) can be reduced such that the extent of the plug housing (here the first part 2 arranged on the rear side of the mounting plate 1) is smaller than the distance to be held, so that there is still sufficient room for soldering the contacts 29 on the plug-in connector side.
Fig. 21 is a perspective view from the front of the mounting board 1 of another insert connector and cable insert connector arrangement, wherein the prior art current signal input insert connector 25, the current signal input insert connectors shown in fig. 12A-12D, the current signal output insert connectors shown in fig. 11A-11D, and the prior art current signal output insert connector 26 are arranged alongside one another. In addition, a prior art cable plug-in connector 27 is inserted into each of the two current signal output plug-in connectors.
The conventional current signal input plug-in connector 25 and the two plug-in connectors according to the invention in turn each meet the requirement of a so-called D-size.
Fig. 22A, 22B, 22C are three different side views of a prior art current signal input cable plug-in connector 27, fig. 22D is a top view from the perspective of the mounting plate when inserting a plug into the plug-in connector, and fig. 22E is a top view from the perspective of the mounting plate when inserting a plug into the plug-in connector.
The cable plug-in connector has a latch slide 30 comprising a latch 31 for latching into a latch socket 11, 11″ of the current signal output plug-in connector. Furthermore, four key elements 32, which are embodied here as recesses, can be seen, which are suitable for co-acting with the key fittings 10, 10″ of the plug-in connector, which are embodied as flanges.
Fig. 23 is a perspective view of the current signal input cable plug connector of fig. 22A-22E, with one side adapted for insertion into the embedded plug connector highlighted. In this highlighted section, a section 33 extending perpendicularly to the axis or slightly obliquely perpendicularly to the axis is just visible for one of the grooves, which section in the locked position catches behind the flanged key fitting 10, 10″ of the plug-in connector, so that accidental axial extraction of this cable plug-in connector is prevented.
Fig. 24 is two perspective views (fig. 24A, 24B) and one side view (fig. 24C) of the current signal output embedded plug-in connector of fig. 1A-1D with the cable plug-in connector mating piece 27 inserted, as seen from the front of the mounting board 1. The locking slide 30 or the locking bolt 31 of the cable plug connector 27 is in the locking position, so that the cable plug connector is prevented from pivoting (in the opposite direction to the screwing direction).
Fig. 25 is two perspective views of the cable plug connector 27 of fig. 22A-22E, wherein the latch slider 30 or latch 31 of the cable plug connector 27 is in an open (un-snapped in) position in one view (fig. 25A) and in a snapped in position in the other view (fig. 25C). In addition, this figure shows a side view of the latch slider 30 with the latch 31 (fig. 25B).
Fig. 26 is three different side views of a prior art current signal output cable plug-in connector 34 (fig. 26A, 26B, 26C), a top view from the perspective of the mounting plate when a plug is inserted into the plug-in connector (fig. 26D), and a top view from the perspective of the mounting plate when a plug is inserted into the plug-in connector (fig. 26E).
The cable plug-in connector has a latch slide 30 'comprising a latch 31' for latching into a latch socket 11', 11' "of the electrical current signal input plug-in connector. Furthermore, four key elements 32', which are embodied here as flanges, can be seen, which are suitable for co-acting with key fittings 10', 10' "of the embedded plug-in connector, which are embodied as grooves.
Fig. 27 is a perspective view of the current signal output cable plug connector 34 of fig. 26A-26E, with one side adapted to be plugged into the embedded plug connector highlighted. In this case, the flanges serve as key elements 32' and serve to prevent axial extraction of the cable plug-in connector in the fully screwed-in state when the flanges are subsequently located in grooves of the plug-in connector which extend perpendicularly or slightly obliquely to the axis.
Fig. 28 is a side view (fig. 28A) and a perspective view (fig. 28B) of the current signal output embedded plug connector of fig. 11A-11D with the cable plug connector mating member 27 inserted, wherein the position of the top cover 17 pressed against the cable plug connector 27 is highlighted. This cover is constructed resiliently in such a way by means of the pivot joint 18 that it moves itself to the closed position, so that in the case of a plug-in cable connector, this cover presses against the plug-in cable connector 27.
According to one aspect of the invention, the harder cap edge 19 (compared to the elastomeric sealing enclosure 22) rests on the cable-plug connector, wherein the cap edge 19 resting on this cable-plug connector is adapted to, for example, in the closed state of the cap, promote a labyrinth seal in order to dampen splashes before they strike the sealing enclosure 22.
Fig. 29 is a perspective view (fig. 29B) from below and a second partial flange 5 "(fig. 29A) with a top cover 17 fixedly arranged on the second partial flange, a perspective view (fig. 29C) from above in the closed position of the top cover, and a side view (fig. 29D) of the closed position of the top cover for use in the insert type connector shown in fig. 11A-11D.
In the view from below, it can be seen, for example, that the sealing element 24, which is produced, for example, by means of 2-component injection molding, is pressed when the flange is mounted on the mounting plate 1. It can furthermore be seen that the sealing element 24 here also seals a bore 35 (of the blind bore leading to the first partial flange) which is suitable for mounting the flange to the mounting plate. Furthermore, the bore 35 is also surrounded by the sealing collar 22 or the sealing collar fitting 23.
Fig. 30 shows a top view of the second part flange 5″ with the cover 17 of fig. 29 and two sectional views differing by ninety degrees.
Fig. 31 is a perspective view of the second part flange 5″ with the top cover 17 shown in fig. 29, wherein this top cover is not fully closed and the view around one of the bores 35 adapted to be mounted on the mounting plate 1 is highlighted.
This highlighted view particularly shows that the seal-enclosure fitting 23 encloses (i.e., seals together) the bore 35. This view also shows the top cover edge bearing surface 20 and the projection 21, which provide a labyrinth seal effect in a manner that cooperates with the top cover edge 19.
Of course, the figures shown only schematically show possible embodiments. The different means may also be combined with each other and with the prior art methods.
